While the device is charging, the touch screen may
not function due to an unstable power supply. If

the power outlet or unplug the USB cable from
the device.
3. When the battery is fully charged, first unplug the
USB power adapter and USB cable from the device
and then from the power outlet.
To save energy, unplug the USB power adapter
when not in use. The USB power adapter does not
have a power switch, so you must unplug the USB
power adapter from the outlet when not in use
to avoid wasting power. The USB power adapter
should remain close to the socket when in use.
